Power Requirements

• Power Consumption: Max 650mA/5VDC

Grounding

The G2C1 module requires a 5V DC input, +/- 5%, on jumper J3. At boot-up, it uses a maximum of 650 mA with no external devices attached. If the module is supplying power to external USB devices (500mA max.), the input power should be a minimum of 5.15 V to meet the USB specification at the far end of the longest USB cable run. The module can also supply +5V to other external devices on some of the connectors, and all such supplies need to be considered in the power budget. The input power connector can handle 3A of nominal 5V input. The module can also be powered via the USB OTG connector. Please consult Reach Technology for requirements to power this way.

The board mounting holes are connected to a digital ground. These must be connected to a chassis ground either directly or through a transient protection diode for ESD. The resistive touch circuit has ESD protection that shorts ESD on the touch panel to the board mounting holes.

Mounting Options

Gaskets are available, visit Mounting Options for more information.

Software Releases

Download a new software release by selecting the appropriate model and kernel image from the table below (usually the latest version). Then visit the SD Card section for a discussion on tools you can use to install the new software on your SD card.

Part Number	Date	Change Log	File Size	Image	Software Documentation
S001-010	09/23/2015	New Boot Logo. Added Time Zone Support.	153 MB	S001-010	G2C-V1-0
S001-009	05/04/2015	Added drivers for Projected Capacitive touchscreen.	161 MB	S001-009
S001-008	04/03/2015	Not released.
S001-007	01/13/2015	Added a GPIO Demo. Upgraded the QML Demo. Added System Plugins Demo. Added Ethernet IO Agent. Added Generic IO Demo. Made RS485 Fixes. Made Numerous Bug Fixes.	152 MB	S001-007
S001-006	03/19/2014	Added Qt Webkit Open Source web browser engine. To reduce root file system size, the Samba file server slimmed down to a minimal version.	149 MB	S001-006
S001-005	03/06/2014	Added new QML chart plugin. Updated QML demo to show various charting examples. Added a new flash upgrade script. The SD card image now contains the necessary bin files for programming the flash. This ensures that with each release the SD card and flash software versions are in sync. Please note that the flash upgrade tool does not copy the contents of the SD card to flash. The flash upgrade is essentially a factory reset for the current version. Note: The downloadable images are now compressed using zip. Once downloaded unzip and then write the [Release].img file to an SD card.	167 MB	S001-005
S001-004	02/20/2014	Disabled use of /etc/timestamp for setting the HW Clock. The system date is now set only by the HW Clock. Detailed Explanation: On orderly shutdown, Linux was writing the last known time to /etc/timestamp, and then on power-on, it compared the time from HW real-time clock with the file value and set system time to the “lastest” of the two. The problem is, if the HW clock battery dies, the “later” time is invalid but might only be off by an hour or a day and not enough to draw attention, but if the application is doing time/date data logging this could be enough to mess things up. By making it rely on the HW clock only, if the date is wrong it will be 1970 which should be obviously wrong.	268 MB	S001-004
S001-003	02/10/2014	Added QML plugins to support sound (beeper), LCD backlight level setting, and Real Time Clock (RTC) date/time.	268 MB	S001-003
S001-002	01/13/2014	Added screen rotation for QML. Added “yellow touch indication” on QML demo. Added UART2 on J9. Removed daemon flag on SIO Agent.	272 MB	S001-002

Accessories

Consider getting a microSD card extension cable if you are doing a lot of development and frequently replacing the microSD card in your module.

Other accessories come with Development Kits. However, some customers need additional items for prototyping. In that case, items can be purchased online by model.
